Vet Triage Chat Bot
CatMD is your cat's voice in your pocket.
The more you use it, the more it becomes your cat. Every check-in, photo, named person, and body-language read sharpens the cat that lives in the app โ the one who writes a diary every night, sends postcards in their own voice, drops a daily card to your home screen, and replies when you chat. After a few weeks, the diary and chat stop sounding like "an AI" and start sounding like the cat at home. Plus vet-grade triage when something feels off. Built for cats only.
๐พ TODAY โ 15-second check-in (mood, appetite, litter). 6-second body-language reads with channel-by-channel interpretation. Health Rhythm spots drift before symptoms.
๐พ BOND โ Where your cat takes shape. โข Personality: 9 archetypes from the Litchfield Feline Five โข Daily Diary in your cat's voice โ references recent days, named family, things you've told them โข Daily Card: today's vibe, ready to share โข People & Pets: tag who's in the photos; names get woven into the diary โข Becoming: 7-facet identity score showing how shaped your cat is in here โข Posters: a new theme every week โ movie hero, famous painting, Studio Ghibli scene, 80s anime
๐พ CHAT โ Your cat replies in their own voice. First-person, in their archetype, with the day's mood (grumpy, mischievous, theatrical, philosophical, megalomaniac โ resets at midnight). They remember the diary, named people, and things you've told them about themselves. Every reply is screenshot-worthy. Vet-grade safety net when symptoms come up.
๐พ TRIAGE โ 60-second photo + symptom scan with a 0โ99 score and 4 urgency tiers. Feline Grimace Scale (Univ. Montreal 2019). Sleeping respiratory rate monitor for HCM. Vet-ready PDF export.
WHY CATMD? AI that knows YOUR cat โ breed, personality, named family, diary, mood arc, self-facts. Cat-only. Private by design. Daily ritual, not crisis tool.
โ ๏ธ Informational only. Not veterinary advice. In an emergency, contact your nearest vet immediately.
ExpressJSCatMD.pet's answer:
CatMD started with a 2 AM Google search โ the kind every cat parent knows. The cat is acting "off," the forums offer contradictory anxiety, and the only symptom checkers available treat cats like dogs in smaller bodies. Amit Raina, the founder, is a Singapore-based solo developer with nearly a decade of consumer-app experience and a household run by cats. He couldn't accept that "better information when it matters most" wasn't a solvable problem. CatMD is the answer to that night: cat-only, vet-source-cited, structured enough to be useful at 2 AM and again at the vet's office the next morning.
CatMD.pet's answer:
CatMD is the only AI vet triage app built exclusively for cats โ not a generic pet app retrofitted. Its knowledge base is curated from five peer-reviewed feline-only sources (Merck Veterinary Manual, AAFP, Cornell Feline Health Center, ISFM, ASPCA Poison Control), and its outputs include the Feline Grimace Scale (research-grade pain scoring from a single photo), a sleeping respiratory rate monitor (early heart-disease signal), and chronic-condition dashboards for CKD and hyperthyroidism. Every triage produces a 0-99 health score with a clear urgency recommendation โ Emergency, Vet Soon, Monitor, or Low Concern โ in under 60 seconds.
CatMD.pet's answer:
Most pet symptom-checker apps (Petriage, Buddydoc, TTcare, PawScan AI, Maeve by Barkibu) are generic across all species, which dilutes signal for cat-specific conditions. The closest cat-focused competitor (Sylvester.ai) does pain assessment only. CatMD is the only product that combines cat-only knowledge depth + structured 0-99 scoring + Feline Grimace Scale + sleeping respiratory rate + CKD/thyroid dashboards + vet-ready PDF export + anonymous-by-default UX. The decision support is calibrated specifically to feline biology and behavior, not "averaged" across species.
CatMD.pet's answer:
Anxious cat caregivers โ owners who notice their cat acting "off" but aren't sure if it's serious enough for a vet visit. Cats are masters at hiding illness, so caregivers often face uncertainty (delayed vet visits, unnecessary ER trips, late-night Google spirals). CatMD's primary users are typically multi-cat households, owners of senior or chronically-ill cats, and first-time cat parents. Secondary audience includes veterinary professionals who want a structured pre-visit triage report from clients.

React Native + Expo (Android-first, iOS in progress), Supabase for auth and cloud sync, RevenueCat for payments and entitlements, PostHog for product analytics, OpenAI's gpt-4o-mini for triage reasoning (with gpt-4o for emergency-level escalation), and a custom feline knowledge pipeline that ingests peer-reviewed veterinary references and applies VCPR/FDA-compliant prompt guardrails. Hosted on Cloudflare Workers (catmd.pet) for the proxy layer. Closed beta on Google Play; iOS TestFlight planned post-Android public launch.

Many REST frameworks also ship with limited security controls enabled by default. Express.js , a minimal web framework, does not include rate limiting or input validation out of the box and relies on middleware for these concerns. Django REST Framework includes throttling features, but they are not enabled by default. - Source: dev.to / 3 months ago
